Use this method:

public byte[] convertImageViewToByteArray(ImageView image){
    Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
    return stream.toByteArray();
}

Note: The method assumes that the image was assigned to ImageView with android:src . If you were android:background instead of

image.getDrawable()

use

image.getBackground()
